Beginners (6-7 years old): The game is played with smaller teams and a simplified castle (fewer stones or cups). Attackers focus on knocking down and rebuilding with guidance from the teacher, while defenders observe and tag carefully. Children are encouraged to verbalize their decisions (“I will rebuild here because…”) and reflect briefly on what worked or didn’t. This level develops basic critical thinking by helping students notice patterns, evaluate immediate options, and make simple strategic choices while feeling safe to experiment.

Advanced learners (8-9 years old): Teams are larger, and the castle is full-sized. Attackers and defenders are encouraged to plan multiple moves ahead, considering not only immediate consequences but also possible reactions from the other team. Children discuss potential strategies with teammates, test hypotheses during play, and adapt in response to opponents’ actions. This level strengthens analytical reasoning, situational awareness, and flexible problem-solving, while fostering collaboration and critical reflection on outcomes.

Experts (9–10 years old): The game is played with full teams in larger play areas, with added complexity such as time limits, multiple castles, or variable rules (e.g., certain zones cannot be crossed, or only certain players can rebuild). Attackers and defenders must coordinate advanced strategies, anticipate counter-strategies, and make split-second decisions. Children are encouraged to observe, analyse, and critique their own strategies and those of opponents, discussing what worked and why. This level intensively develops critical thinking, strategic planning, and adaptive decision-making under dynamic conditions.
